“…Total phosphorus (TP), total nitrogen (TN), ammonia nitrogen (NH 4 + ‐N), organic matter (OM, represented by loss on ignition) and pH for all collected bulk and rhizosphere sediment samples were determined as previously described (Jiao et al, 2020; Zeng et al, 2016). Sediment moisture content (MC) was determined gravimetrically before and after lyophilization (Ding et al, 2020). The particle size distribution (clay, silt and sand) of each sediment sample was measured using a Laser Diffraction Particle Size Analyzer (LS13320; Beckman Coulter).…”

“…Sediment moisture content (MC) was determined gravimetrically before and after lyophilization (Ding et al, 2020) We performed an amplicon survey of the 16S rRNA gene of bacteria using the pair primers 515F (5′-GTGCCAGCMGCCGCGGTAA-3′) and 806R (5′-GGACTACHVGGGTWTCTAAT-3′) targeting the V4 hypervariable region (Caporaso et al, 2012). The polymerase chain reaction (PCR) amplification was performed in triplicate for each sample within a 20 µl mixture using the protocol described in our pervious study (He et al, 2020).…”

Comparison of the spatial distribution and assembly processes between bulk and rhizosphere bacterial communities at multiple spatial scales is vital for understanding the generation and maintenance of microbial diversity under the influence of plants. However, biogeographical patterns and the underlying mechanisms of microbial communities in bulk and rhizosphere sediments of aquatic ecosystems remain unclear. Here, we collected 140 bulk and rhizosphere sediment samples of Phragmites australis from 14 lakeshore zones across a 510‐km transect in the Middle–Lower Yangtze plain. We performed high‐throughput sequencing to investigate the bacterial diversity, composition, spatial distribution and assembly processes of these samples. Bacterial communities in the rhizosphere sediment exhibited higher alpha diversity but lower beta diversity than those in the bulk sediment. Both bulk and rhizosphere sediment bacterial communities had significant distance–decay relationships, but spatial turnover of the rhizosphere sediment bacterial community was strikingly lower than that of bulk sediment. Despite variable selection dominating the assembly processes of bacterial communities in bulk sediment, the rhizosphere of P. australis enhanced the role of dispersal limitation in governing bacterial communities. The relative importance of different ecological processes in determining bacterial assembly presented distinct patterns of increasing or decreasing linearly with an increase of scale. This investigation highlights the convergent selection of the aquatic plant rhizosphere for surrounding bacterial communities and emphasizes the importance of different ecological processes on bacterial community assembly in sediment environments over different scales. Furthermore, we provide a preliminary framework for exploring the scale dependence of microbial community assembly in aquatic ecosystems.

“…81 Notably, several trophodynamic studies showed that some OPEs such as TCEP, TCIPP, TDCIPP, TIBP, TNBP, TBOEP, TPhP, and TMTP could be biodilute in marine/lake food chains from the low-middle latitude regions (Table S5). 9,79,117 In general, current studies on biomagnification of OPEs mainly focus on the aquatic food webs, and limited findings are inconclusive. Therefore, biomagnification potential of OPEs should be investigated further through not only aquatic food webs but also terrestrial food webs.…”

Organophosphate esters (OPEs) have been a focus in the field of environmental science due to their large volume production, wide range of applications, ubiquitous occurrence, potential bioaccumulation, and worrisome ecological and health risks. Varied physicochemical properties among OPE analogues represent an outstanding scientific challenge in studying the environmental fate of OPEs in recent years. There is an increasing number of studies focusing on the long-range transport, trophic transfer, and ecological risks of OPEs. Therefore, it is necessary to conclude the OPE pollution status on a global scale, especially in the remote areas with vulnerable and fragile ecosystems. The present review links together the source, fate, and environmental behavior of OPEs in remote areas, integrates the occurrence and profile data, summarizes their bioaccumulation, trophic transfer, and ecological risks, and finally points out the predominant pollution burden of OPEs among organic pollutants in remote areas. Given the relatively high contamination level and bioaccumulation/biomagnification behavior of OPEs, in combination with the sensitivity of endemic species in remote areas, more attention should be paid to the potential ecological risks of OPEs.

“…Statistics show that, for the 16 individual PAHs BSAFs, difference between marine organisms were signi cant (shell shes > shes > shrimps > crabs (nonparametric-test, p < 0.01). These difference of BWAFs/BSAFs may be related to the feeding habits and trophic levels of marine organisms, previous studies have found that in the tropical marine food web, persistent organic pollutants are diluted rather than ampli ed (Ding et al 2020). In this study, marine organisms including mollusks (oysters), mainly lter and feed on microalgae and organic debris in the ocean, the majority shes (Tilapia mossambica, Rhabdosargus sarba, and Trachinotus ovatus) are omnivorous, mainly feeding on plant food, algae and benthic invertebrates, and the crabs and shrimps are carnivorous, are carnivorous, mainly feeding on benthic invertebrates.…”

The coastal zone is the crucial transitional zone between the ocean and the land. Under the in uence of global climate change and human activities, the coastal zone is suffering from huge environmental pressure. It is necessary to pay close attention to the pollution of PAHs to coastal ecological environment and the risk to human health. Taking the Beibu Gulf coastal zone as an example, we investigated the pollution status of PAHs in various environmental media. Results showed the total concentration of 16 PAHs (Σ 16 PAHs) in winter were signi cantly higher than that in summer. Compared with the coastal area, the pollution of PAHs in the estuarine area is more serious: the Σ 16 PAHs in estuarine waters (summer: 71.4 ± 9.58 ng/L; winter: 96.8 ± 24.7 ng/L) > coastal waters (summer: 50.4 ± 9.65 ng/L; winter: 91.7 ± 18.9 ng/L); estuarine sediment (146 ± 116 ng/g) > coastal zone (76.9 ± 108 ng/g). The source apportionment results indicated that spilled oil, biomass and coal burning were the main sources of PAHs in water, whereas the primary sources were spilled oil, fossil fuel burning and vehicle emissions in sedment. Shell sh showed the highest average PAHs concentration, followed by sh, shrimp, and crabs.The calculated bioaccumulation factor indicates that the seafood has a low bioaccumulation capacity for PAHs in the ambient environment. Human health risk assessment shows that accidental ingestion of PAHs through the consumption of seafood generally does not pose a health risk, but children should properly control the intake of shell shes.
